SubGhzProtocolCAME

Hi, sorry for that, but what is te_delta ?? @SkorP

#define TAG “SubGhzProtocolCAME”

static const SubGhzBlockConst subghz_protocol_came_const = {
.te_short = 320,
.te_long = 640,
.te_delta = 150,
.min_count_bit_for_found = 12,
};

inaccuracy in the transmission of duration by the transmitter. depends on the battery charge and frequency accuracy of the quartz in the transmitter

@SkorP I am curious how you find those values. Do you estimate based on different samples?

analysis of many records and common sense. If you have any other way, I’d love to hear it.

Unfortunately not. I am currently looking at a protocol of a device which I don’t own. Signals from to different devices deviate so much, I am not even sure they are the same model.

look at the next topic, I tried to tell there how I analyze an unknown protocol

I appreciate your usual follow up and replies!

I notice when I tried to record multiple key fobs using 24bit CAME protocol, that there is a difference in the pilot period comparing with 12bit. for the 24bit its around 88x instead of 36x, which is really strange for me, are you aware of any difference between 12bit CAME and 24bit ?? as when I read the signal from original key fob it got recognized as 24bit CAME but it never worked on the actual gate.

show RAW recordings of remotes 24 and 12 bits CAME

yes you are right i will fix it now

@BitcoinRaven
you can check? is everything working right now?

I need to do further testing to confirm, Im away of the gate at the moment for a couple of days. May I ask what software do you use for plotting?
